RIP Challenger. Remembering the explosion, 30 years later #NASA

RIP to all seven crew members aboard the Challenger, which devastatingly blew up 30 years ago today:

(CNN)Much like the assassination of President John F. Kennedy, or the morning of September 11, 2001, most Americans remember where they were when they heard the news of the Challenger disaster.

It was NASA’s first in-flight tragedy. Challenger launched from Kennedy Space Center in Florida on January 28, 1986. Shortly after liftoff, the space shuttle’s external fuel tank collapsed, causing what looked like an explosion, and the shuttle broke apart and fell.
